You can download files with all the delegation info from ftp.arin.net.
You mean the stats files, which provide delegation date, type, starting number, length, etc.?
Which one of the published fields is the key field that enables you to identify the common recipient(s) of successive delegations over time?
There is no such field.
No, simply because large ISPs need lots of addresses, everyone else can make do with just a few.
But in the absence of some other metric for largeness, that sounds like a tautology. Large ISPs are the ones that demand lots of addresses... ergo to demand a lot of addresses is to be large...
You've got a point there. However, I think many of us will be able to judge ISP size from other factors and observe that the correlation by the such determined ISP size and address use is quite high.
To turn things around: does anyone know about a significant amount of address space (say, a block of a million or so or more) going to an entity that isn't an ISP of some sort in the past 5 years?
